IMPROVEMENT IN DISINFECTING APPARATUS FOR WATER-CLOSETS, 6c.

Specification forming/parilwetters Patent No. 222,519, dated December 9,1879 5 application filed October 22, 1879.

To all whom it maj/fc/oncm.:

` Be it known that I, EDWARD J MALLETT, Jr., of the city, county, andSta-te of New York, have invented a new and useful Improvement inDisinfecting Apparatus for Water-Closets, dto., which improvement isfully set forth in the following specification, reference being had tothe accompanying drawings,

one appertaining to what I call the liquid disinfector, and the other tothe aerial disinfector. Through the side of the vessel A extend twopipes, c d, one above the other, and in applying my apparatus to acloset the upper pipe, c, is connected with a water-service pipe,

or with-a tank, as the .case may be, and otherwise so arranged thatwater constantly drips into the vessel A through this pipe, or, in otherY of said pipes.

words, so that a continuous supply of water is maintained. The other orlowerp'ipe, d, at the saine time is connected to the bowl K of thecloset, orto the water-supply pipe or the soilpipe, so astedischargeinto the bowl or either The vessel Aisthen lled withdisinfecting material, such as chloride of Zinc,

" and as the water drips into the vessel from the supply-pipe c,itis'charged with or becomes a` solution of such material.` When theliquid disinfectant thus formed reaches the level of the piped,itloverflows by means of this pipe, and is thereby conducted to thecloset bowl or pipe. In this manner the closet is constantly iiushedwith a disinfectant, which prevents the local manufacture of gases andstamps out any gases that attempt to enterfrom the sewer.

2 let.

Into the vessel B project two pipes, f g, one forming an air-inlet, andthe other an air-out Said vessel B is, supplied with a disinfectant,such as a solution of thymol, and the arrangement of its two pipes issuch that the air-inlet f terminates below the level of the solution,while the mouth l of the air-outlet g is above such level.

To the vessel B is connected an air suction and forcing device,consisting, in this example, ofA a exible cap, H, which is attached tothe top of the vessel and carries a weight, i, and of a chain, j, or thelike, for lifting the cap up against the action of its weight. When thecap H is lifted up a vacuum is formed in the vessel B, which is at onceiilled with air admitted by the inlet f, and since this incoming air iscaused to pass or bubble up through the thymol or other solution itbecomes charged with its vapor. If the cap H is now released, the samesinks down with the weight fi, and by this means the air, charged orimpregnated with the vapor of thymol or other material, is expelled fromthe vessel B, by the outlet g, into th'e closet-room, the effect ot'which is to maintain thereilran .atmosphere inimical to the propagationof disease-germs, a-nd free from unpleasant odors.

The direction of the pipe f, forming the airinlet, is downward andinward, and since it terminates below the level of the solution in thevessel B it always contains a column of liquid, which acts as a valve inpreventing the escape of the air through the inlet while it is beingforced out by the outlet g. In order to prevent the influx of airthrough the pipe forming the outlet g, this pipe is made of smallerdiameter than the inlet-pipe f; but this can also be accomplished byproviding the outlet with a self-acting valve. The air inlet and outletj' g, moreover, may be formed by valvecovered openings in the top of thecap H, and in that case a sponge or other absorbent may be attached tothe cap in such a manner as to dip into the solution in the vessel B andgive it oft' as a vapor, thereby charging the incoming air. The twovessels A B are connected together, the same being in this examplearranged one within the other, so that they occupy the least possiblespace, and they are sur mounted by a cover, N, which is suitably shapedto allow the motion of the cap H, and which has a slot, o, for thepassage of the chain j, or a lever for operating the chain.

When my invention is applied to a closet having a hinged seat-cover, asat L, Fig. 2, the

chain j is connected to this cover in such a manner that when theseat-cover is lowered, as after using the closet, the cap H is lifted toits upper position, audit-ice versa. The result of this arrangementis;tliat the operation of the cap II is automatic, and the vapor isexpelled from the vessel B during the use of the closet. The chain j,however, may also be connected with the door of the closet, or arrangedto be operated in any other Way.

It is obvious that my invention is applicable to urinals, sinks, andother similar places, as Well as to water-closets, and when it isapplied to a urinal the cap H may be operated by a hinged platformarranged to receive the weight of the person using the urinal.

What I claim as new, and desire to secure by Letters Patent, is-

1. The combination, with a watercloset or the like, of an aerialdisinfector consisting of a vessel for holding the disinfectingmaterial, an air-inlet and an air-outlet to such vessel,

and an air suction and forcing device attached thereto, all adapted foruse substantially as described.

2. The combination, with a water-closet or the like, of a liquiddisinfector connecting with the bowl or other appropriate part of thecloset= and an aerial disinfector communicating with the closet-room,substantially as and for the purpose described.

3. The combination, with the vessels A B, o a water-supply pipe, c, anda discharge-pipe, d, an air-inlet, f, an air-outlet, g, and anairsuction and forcing device connecting with the vessel B, all adapted foruse substantially as described.

In testimony that I claim the foregoing 1 have hereunto set my hand andseal this 20th day of October, 1879.
